Hello is this working, not sure. Hope so. Anyways the problem I have is a bearing noise left side engine compartment and sounds its around the dash area if you put your ear near it. Its a whining bearing noise. Could a bearing in the engine make the noise? Power steering unit? The serp is on the right of me, noise on the left. At idle and parked. 2000 Pontiac Montana
